These instructions will walk you through how to configure your AudioCodes SBC to Voyant Trunking and the Voyant Admin Portal. It will cover using the AudioCodes Configuration Wizard for “SIP Trunk (IP-PBX with SIP Trunk)”. This is a basic guide and will not cover setting up the base PBX or the setup of your extensions and subscriber numbers in detail. Further setup may require you to contact your PBX vendor support, directly, or utilize your PBX vendor forum/community pages.

Note: This guide assumes the SBC is already set up and installed, and that the user has administrator account access to both the SBC and the Voyant Admin Portal.

Trunk Creation

Select the “Create New Endpoint” button to bring up the Endpoint creation wizard.

From here, enter a friendly name for the Endpoint. Enter the public IP address of your SBC. You can choose to change the signaling port and protocol, or leave them at the default of 5060 and UDP. By default inbound and outbound calling are enabled; however, they can be changed at this time.

Once done, press the “Add Endpoint” button.

After closing this screen, you are returned to the main SIP Trunk Creation Screen. If you are satisfied with your choices press the “Create SIP Trunk” button at the bottom of the page.
